Introduced in 2025, the Omega Seamaster Planet Ocean 600M boasts a robust 42 mm case crafted from stainless steel, featuring both polished and brushed finishes. It is protected by a flat sapphire crystal that has an anti-reflective coating on both sides, ensuring clarity underwater. This timepiece is capable of withstanding depths of up to 600 meters (60 bar). The back of the watch, which is a screw-in type, is made from grade 5 titanium and is adorned with the emblem of the Omega seahorse.

A highlight of this model is its striking polished orange ceramic bezel, which includes a diving scale made from white hybrid ceramic. The watch's face showcases a matte black dial accented with rhodium-plated hands and markers filled with white Super-LumiNova, complemented by four orange Arabic numerals. At its heart is the Omega Co-Axial Master Chronometer caliber 8912, which operates at a frequency of 3.5 Hz and features twin barrels in series along with a free-sprung balance utilizing a silicon balance spring. It offers an impressive power reserve of around 60 hours and holds the distinction of being certified as a Master Chronometer by METAS. The Omega Seamaster is presented on a black rubber strap that includes a stainless steel case-link and secures with a foldover clasp.
